Here are a few of my starter images. The point is to do rough stamping, rather than carefully measured and arranged works. The images are stamped on glossy paper (I got mine from Local King Rubber Stamps at a craft show a few years back). The stampscapes site recommends against using photo glossy paper. I'm not sure what the difference is.
Here's a finished card, with foreground, focal images and background images. I've inked it with several shades of blue, and black around the edges, and finished it off with some white gel marker highlights. I mounted it on dark blue cardstock with a black cardstock mat.
